The only Aurora campaign I can think of that actually had a definite conclusion is Kurt's Six Powers Campaign. Haji's From the Ashes ended prematurely, but he gave a pretty detailed plan of how he would have wanted to proceed and ultimately end. There might be some others, especially since I don't know of many outside of these forums. Aurora really isn't made to force an ending to a game if the player doesn't have one planned out. Unless you straight out lose (which is pretty rare for an experienced player), it can and will go on until the game gets so slow you give up.
